This invention relates to tools intendedr for use in connection with stove pipesand the like and has for its object the provision of a novel scraper' adapted to be perma- 5 uently mounted within a smoke pipe and operable at will for scraping out any ac cumulation of soot, fine ashes and the like. It is well known that accumulations of such matter are easily removed from vertilo cal or sharply inclined pipes by simply tapping them with some object so as to dislodge the soot and ashes but in the case of horizontal pipes it is a difficult matter to effect cleaning except by removing the pipe 15 and dumping out the matter therein. lit is with these facts in view that we have designed the present invention which has for its object the provision of a scraper intended to be mounted within a smoke pipe and carried by an operating rod or handle whereby it may be reciprcoated for the purpose of scraping ofil the accumulations to be removed.

An important object is the provision of a device of this character which is so constructed as not to catch into the seams or joints between successive pipe sections.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, easy to operate,.positive in action, eflicient and durable in service, anda general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure l is a longitudinal Section through a smoke pipe showing the device in applied position,

Figure 2 is a cross section on the line 2 2 of Figure 1, "i5 Figure 3 is a detail section through the device itself, and,

Figure 4 is an enlarged detail View taken at right angles to Figure 3.

Referring more particularly to the dravvings, the letttr A designates the wall of a chimney or the like having the usual opening B therein within which is located one end of the smoke pipe indicated at C. As is customary, an elbow D is connected with the outer end of this smoke pipe and establishes communication with -a down-pipe. In carrying out the invent-ion we provide a scraper comprising a body member 10 Which is of crescent shape and which may@ n inactual practice, be constructed as a cast mi ing. The intermediate portion of this body or casting is somewhat enlarged as indicated at 11 while the opposite end portions are preferably tapered off as shown at 12. The enlarged central portion 11 is formed with a suitable hole 18 by means of which the body member is secured to one end of an operating rod 14:, the end of the rod being threaded and carrying a pair of nuts 15 loh cated at opposite sides of and clamped Tf1 against the body. This rod is slidable through a suitable hole 16 in the elbow D and is preferably equipped with a button, knob or other handle member 17.

rlhe device further comprises a hoop 1S f-Y which may conveniently be formed from a single Alength of Wire and which has the ends engaged within thel body member 10, preferably by casting this body about the ends. Obviously, any other desired means @il for effecting connection might bek resorted to within the scope of the invention. Attention is directed to the fact that the lower edge or the outer edge of the body member l0 is convex as indicated at 19 so that when the device is reciprocated within the smoke pipe the body member will not catch against the edges of lsuccessive pipe sections or catch and stick when passing over joints, seams or the like.

The device is intended to be mounted permanently within the smoke pipe and whenever it is desired to remove any accumulations of soot, fine ashes or the like, it .is merely necessary that the operator grasp the 95 handle member 17 and move the rod and consequently the scraper back and forth within the pipe. The matter thus dislodged and loosened may be raked out by means oi the body portion until it drops through the li?" downpipe E into the stove, furnace or whatn ever device the invention is used in conne@` tion With.

From the foregoing description and a study of the drawings it will be apparent that we have thus provided a simply constructed, inexpensive, easily installed and very simply operated device for the purpose specified which will be highly efficient and which will be a great saver of time, labor Il" and annoyance in addition to making it such an easy matter to remove the accumulation of soot and the like that they Will not be `allowed to accumulate and clog the pipe with the resultant Vdanger of re.

1While We have shown and described the preferred embodiment of the invention, it should be understood that We reserve the right to make Such Changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope lof the subjoined cla-im;
